INCINEBATOB.

Application led March 5, 1927. Serial No. 178,022.

This invention relates to improvements in incinerators, more particularly adapted for burning table waste and all forms of rubbish in a very simple and expeditious maii- It is one of the objects of the present iny vention'to provide an incinerator which is particularly adapted for use in hotels, clubs,

. restaurants, stores and other places which have comparatively a large amount of waste material to dispose of. .Y

A further object of the invention is to provide an incinerator having means permittin the agitation 'of the waste material while urning, to admita greater amount of,

air thereto, vto more eliciently and expeditiousl burn the material.

A further object of the invention is to provide an incinerator provided with an auxiliary artition and agitator member which divi es ortons of the waste material to permit thev urning orases to better penetrate into the mass of burning material.,

A further object of the invention is to rovide an incinerator in which the grate is divided into sections to permit the independent turning of the sections or only one of the sections when a small amount of material isv bein consumed.

A further obJect of the invention is. to provide an incinerator havin means for preventing the waste material rom block' the passage of the burning gases aroun sides of the material.

A further object of the invention is to provide an incinerator usinggas as the fuel medium in which the fuel pipe also serves as the fulcrum for the tiltable grate sections.

A further object of the invention is to provide an incinerator which is of simple construction is strong and durable and is well ada ted for the urpose described.

With t e above an other objects in view, the invention consists of the improved incinerator and its parts and combinations as set forth in theclaims and all equivalents thereof.

In the accompanying drawings inwhich the same reference characters indicate the 5o same parts in all of the views:

Fig. l is a perspective view of the improved incinerator, parts of the casing being broken away to show interior construction;

.Fig. 2 is a central longitudinal sectional view taken on line 2 2 of Fig. 3;

Fig. 3 is a transverse sectional view taken on line 3 3 of Fig. 2; and

Fig. 4 is a horizontal sectional detail view of a portion of the incinerator taken above the grate bars of.the incinerator. Referring to the drawings, the numeral 8 indicates an outer rectan ular casing which is. formed of sheet meta and is provided with an upper inlet opening 9 closed by a hinged counterweighted cover 10, a smoke pipe opening 9 and lower draft andclean out openings 11 closed by doors 12. The doors 12 are formed with lines of openings 12 to admit air for combustion. The casing is formed with an inner wall-13 of corrugated metal which is spaced from the outer wall to form a heat insulating s ace 111 between the two walls. Fixed grate ars l5 extending downwardly and toward each other at an incline are positioned on opposite' side portions of the casing above the plane of the draft or ash doors 12 to form an ash chamber or compartment 16 below and a lire chamber or compartment 17 above. The space between the inner4 edges of the fixed grate is occupied by the tiltable grate bar sections 18 which are pivotally mounted on burner pipe sections 19. The tilting grate sections, o which there'are preferably two, are formed with bearing collars 20 which loosely surround the pipe sections and turn thereon. with extension bearing portions 20 which extend through and are journaled in the casing 8,. Crank handles 21 are mounted on the proecting portions for convenience in indepen ently rocking the grate sections.

The burner pipe sections 19 at their inner abutting ends are closed and lare connected to and supported by a transverse bracket 22 which extends across the central portion of the grate bars, as shown in Figs. 1, 2 and 3. The outer end portions of the burner pipe sections are connected to elbows 23 which are open at one end to admit air to mix with the gas or other fuel passing therethrough. A pipe 24 supplies gas or other fuel to the burner pipe sections, and the portions of the yburner pipes within the casing are provided with staggered lines of discharge apertures 25 through which the" gas flows.

An agitator member 26 extending longi- The outer collars 20 are formed tudinally of the casing is mounted on a shaft 27 which is journaled at its opposite ends to the opposite ends of the casing and an outer end is provided with a crank handle 28 for turning or rocking the agitator. The agitator is of triangular form in cross section, with the apex of the form normally pointing upwardly, as shown in Fig. 3. Side extensions 26' which extend downwardly in planes in alinement with upper side portions of the agitator member, are formed with parallel elongated slots 29 which aline with the slots 40 forming the grate bars 15 and 18 to permit the burning gases to pass therethrough. For convenience of manufacture the agitator member is formed of two half portions bolted together around the shaft 27. The lower edges of the extensions 26 are spaced apart approximately a distance corresponding to the width of the tiltable grate bars and are spaced thereabove a suiicient distance to clear the path of movement of the tiltable grate sections and to also clear the transverse bracket 22 when said agitator is rocked. The location and shape of the parts just mentioned form a very important part of the invention, as the said parts form a combustion space 30 between the grate bars l5 and 18 and the agitating member 2,6, so that some of the burning gases flowing upwardly through the grate bars will enter the space 30 and heat and burn the rubbish at the central portion of the mass within the incinerator as well as around the outer portions of the mass. The burning gases directed into and through the central portion of the m/ass as well as around the outer side of thelmass will more quickly and elliciently heat and burn the mass than if the gases were only directed against the outer side thereof. The provision of the tiltable agitator member also permits the stirring up of the inner portion of the rubbish in case the rubbish is too densely packed to freely burn.

The angular formation of the agitator member and its spacing from the grate bars acts as an automatic feeder, as the material in burning and settling will gradually drop into the side portions of the combustion space partly beneath the agitator, and will be consumed bythe hot gases. The elongated slots 29 in the agitator side extensions 26 permit the flow of hot burning gases therethrough and into the central portion of the mass of material, with the result that they moisture is quickly evaporated from the mass and the material close to the extensions will then start to burn, and the heat of this burning will augmentthe heat of the burning gases and thus conduce to the more eilicient burning of the mass.

The agitator while forming in part the combustion space permits some of the waste material to separate from the mas and drop into the combustion space, where it will be 1. An incinerator, comprising a casing,

grate bars dividing the casing into a lire chamber and an ash chamber, and an agi- `tator member comprising a body portion having spaced apart side extensions forming a space between said body portion and said side extensions extending into the fire chamber above the grate bars to form a combustiony space between the agitator/member and said grate bars.

7. An incinerator, comprising a casing, grate bars dividing the casing into a fire chamber and an ash chamber, and an agitator member comprising a body portion having spaced apart and perforated side extensions extending into the fire chamber above the grate bars to `form a combustion space between the agitator member and saidv grate bars.

8. An incinerator, comprising a casing, grate bars dividing the casing into .a iire chamber and an ash chamber, and an agitator member 'of approximately A-shape in cross section positioned in the iire chamber above the grate bars to form a combustion chamber between the said agitator member and the grate bars.
